"Ghostbusters 3" is set to begin production in less than a year and will "hopefully" bring back Bill Murray, says Dan Aykroyd, who appeared with the actor in both of the previous installments of the hit sci-fi franchise.

The pair played Peter Venkman and Ray Stantz, two of four men who investigate reports of hauntings and strap on Proton Packs as they work to nab evil ghosts that wreak havoc on New York City. "Ghostbusters 2" was released in 1989. The third film is tentatively set for release in 2012.

Murray, 60, Aykroyd, 59, and the other two actors who played the remaining two Ghostbusters, Harold Ramis, 67, and Ernie Hudson, 65, are set to reprise their roles in the new film, according to casting lists.

However, Aykroyd said on Miller's show: "The promise of 'Ghostbusters 3' is that we get to hand the equipment and the franchise down to new blood."

"Because my character, Ray, is blind in one eye, can't drive the Cadillac, has a bad knee and can't carry the packs ... Harold is too big ... Egon (Spengler) is too large to get into the harness," he said. "We need young blood. That's the promise. We're going to hand it to a new generation ... production in the spring, I hope."

Dan Aykroyd said the film is going to cast three men and a woman, adding: "I like this guy Matthew Gray Gubler from the 'Criminal Minds' show. We're going to see everyone who wants to do it."

Gubler, 31, has played Dr. Spencer Reid on the CBS crime series since 2005. His spokesperson had no immediate comment about Dan Aykroyd's remarks. The film's studio, Columbia Pictures, has also not commented.

Murray told Howard Stern on the shock jock's Sirius XM radio show in February that there have been talks to recreate the "Ghostbusters" film franchise with younger actors, adding: "It's not a threat. It's sort of business-like. They'd like to keep it going. There's still kids today who watch this movie and love it."
